Instructions
Standing on a bench (or on the floor - for a shorter range of motion), in front of a cable machine with a low pulley. Grab hold of the pulley and keeping that same Side foot ground, step back slightly with the opposite leg, in a staggered stance with the heel of the ground. The front foot remains flat on the ground.
Bracing your core, and locking your shoulders, hinge back at the hips, pushing your glutes backwards. Keep your front knee slightly bent and lower the cable pulley down as low as you can. Come back up to the start position, by pushing your glutes forward. Repeat for the desired number of reps, then repeat on the other leg.
Tips
You do not need a bench to do this exercise, you can do it from the floor, it just may limit your range of motion. Alternatively you can perform it on a small step or bench.
